TFTs / FT5x06 Initial Register Values
« on: January 12, 2016, 05:53:51 PM »
I am using a 4.3" display with the FT5x06 touch controller.  After power-up reset without touching the screen, the registers contain values that indicate at least 1 touch point active and the event flags indicate a "contact" condition.  Sometimes it will power-up indicating more than 1 touch point.  After I touch the screen once, the registers all indicate properly.  I have tried 2 different displays with the same results.

I have tried resetting the display using the reset line, but nothing changes.  It will only indicate properly after I touch the display.

Have you seen this?
